Try this...

```sol4 := fsolve([sol1, sol2], {T = 0...0.5, W = 0...30});

{T = 0.3216117634, W = 29.46435118}
```

Mathematica says the same what a Maple.

Do it this way:...

eval(sum(sum(x^(q-p), p = 0 .. q), q = 0 .. 10), x = 0)

or:

eval(value(Sum(Sum(x^(q-p), p = 0 .. q), q = 0 .. 10)), x = 0)

In Maple 2017 maybe like this:

```J := `assuming`([int(ln(t)^n, t = 0 .. x, AllSolutions = true)], [n::posint])
```

for n=1:

`value(eval(J, n = 1))`

is:

`x*ln(x)-x`

Only works for alpha 1 and 2- symbolic s...

QDifferenceEquations packed is only do algebraic calculation.

From wikipedia: qgamma = (1-q)^(1-z)*(product((1-q^(n+1))/(1-q^(n+z)), n = 0 .. infinity))

qgamma := proc (z, q) options operator, arrow; (1-q)^(1-z)*(product((1-q^(n+1))/(1-q^(n+z)), n = 0 .. 1000)) end proc

z := .8; q := .9

evalf(qgamma(z, q)) =1.156991553

eq1 := 1 = abs(1/(I*Pi*z*(1+I*Pi*a)));
eq2 := -(5/9)*Pi = argument(1/(I*Pi*z*(1+I*Pi*a)));

fsolve([eq1, eq2], {a = 0 .. 1, z = 0 .. 1})

{a = 0.5612662116e-1, z = 0.3134740437}
